Hi,
Subject: [PATCH] ide id updates
From: Jens Axboe <address@hidden>
Date: 1136375788 +0100
Some changes to the ata/atapi identify code and default values:
- Store the drive id in the IDEState, so we can reliably set and query
new values. Right now doing things like:
doesn't work, as the IDENTIFY command will re-fill default values
everytime.
- Fill in IORDY, dma timings, and mdma modes.
- Don't set both 1 << 14 and 0x4000 for word 93, it's the same thing.
- Fill in supported/set ata specs
- Implement real setting of transfer mode (sub feature 0x03 of
WIN_SETFEATURES) so we can reflect the transfer mode requested by the
OS.
With this patch, Linux correctly identifies and sets DMA mode in the
drive by default.

Subject: [Qemu-devel] qemu-smp guest on monoCPU host: big slowdown
To: address@hidden
Message-ID: <address@hidden>
Content-Type: text/plain; charset=ISO-8859-1
Hello
I'm trying to use the new -smp option.
host: win2k
guest: linux 2.6.13-SMP
The first sight is a really big slowdown.
with -smp 2, the guest seems to go approximatively to 1/4 speed of a
monoCPU guest.
I tried to boot with -smp 8, but it was so slow that I abandoned.
Am I doing something wrong?
Is it unavoidable? Some options to use to compile qemu, or to
compile the SMP kernel?
Thanks for all informations

To: address@hidden

<address@hidden >
Content-Type: text/plain; charset="US-ASCII"
Hi everyone,
I am using the current CVS (HEAD) version of qemu running on x86 linux,
and am using it to emulate an ARM on the integrator board, running
arm-linux, using arm-test-0.1.tar.gz.
>From what I've read in this list (
http://lists.gnu.org/archive/html/qemu-devel/2005-12/msg00137.html) , it
should be possible to set up a network, user-mode or TUN/TAP. However, I
fail to see the light as to how to bring the correct interface up on the
guest system (arm-linux). ifconfig shows two devices, lo and dummy0, but
nothing that would point to a smc91 being detected or used. This is
independent from whether I try -net tap or -net user.
1) Is the network/smc91x support finished enough to be useable?
2) If so, what is the magic bullet? Any boot options that I need to give
to the kernel? (BTW, I am calling the emulation as
qemu-system-arm -kernel integratorcp.zImage -initrd arm_root.imfg
-nographic -net user )
Thanks much for any help,
Wolfgang

Message-ID: < address@hidden>
Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed
I made a proposal some month ago based on xml:
http://lists.gnu.org/archive/html/qemu-devel/2005-08/msg00034.html
I use this style of xml property lists for the configuration of the
vm of Q (slightly alter by now).
Q is a OS X port of QEMU http://www.kberg.ch/q
I ran recently into some troubles with arguments that can appear
multiple times, like -net and -redir.
I'm now about to changes my configuration files. Having a well
defined style of configuration files would help making simple guest
packages, that could be used on multiple systems...

-net nic -net user, or no -net option at all. You need a network card
on the VLAN, and also a connection ("user") to the outside.
